CO2-laser in the removal of a plexiform neurofibroma from the eyelid

We present a child with neurofibromatosis type I (NF-I) who underwent excision of a large upper lid neurofibroma using a CO2-laser. Plexiform neurofibromas are notorious for their bleeding tendency and the inability to achieve complete surgical excision. The CO2-laser is an adjunct to achieving better hemostasis and delineation of the tissue in the absence of natural tissue planes caused by the tumor's diffuse mode of growth. Using the CO2-laser achieves better cosmesis, while reducing operation time and limiting complications

Refractive outcomes after phacovitrectomy surgery

Purpose To evaluate the refractive accuracy of intraocular lens (IOL) power calculation after phacovitrectomy. Setting Eye Hospital Zonnestraal and Department of Ophthalmology Academic Medical Center, Amsterdam, the Netherlands. Design Retrospective comparative case series. Methods Refraction results 1 month after phacovitrectomy or phacoemulsification were compared with predicted refractions calculated using the IOLMaster 500 and the Haigis formula. Indications for vitrectomy were macular pucker, macular hole, vitreous floaters, vitreous hemorrhage, and vitreomacular traction. Enrolled eyes had an axial length (AL) between 20.13 mm and 29.43 mm. Results The phacovitrectomy group comprised 133 eyes (133 patients) and the phacoemulsification group, 132 eyes (132 patients). The refractive outcomes after phacovitrectomy (−0.06 diopter [D] ± 0.50 [SD]) and phacoemulsification (−0.08 ± 0.47 D) were comparable (P = .74). The final postoperative refraction was within ±1.00 D of the preoperative refractive target in 94.9% and 94.6% of phacovitrectomy cases and phacoemulsification cases, respectively. Subgroup analysis found no increased risk for refractive surprises after gas tamponade or in eyes with an AL of 26.00 mm or greater. Conclusions Standard IOL power calculation used in regular phacoemulsification surgery was accurate in phacovitrectomy procedures in eyes with a wide range of AL and a wide range of vitrectomy indications. No tendency toward a myopic shift was foun

In-the-bag decentration of a hydrophilic radially asymmetric multifocal intraocular lens secondary to capsule contraction.

Item does not contain fulltextWe report a case of in-the-bag decentration and tilt of a hydrophilic rotationally asymmetric multifocal intraocular lens (IOL) of the M Plus type secondary to capsule contraction. After uneventful surgery and follow-up for 3 months, progressive decentering and tilting of the IOL secondary to capsule contraction and capsulorhexis phimosis was noticed. A surgical procedure was necessary to restore correct centration of the IOL. The uncorrected distance and near visual acuities were restored to logMAR 0. Hydrophilic multifocal IOLs of this specific design may be sensitive to postoperative decentration. Capsular tension rings may alleviate the problem in a secondary repair procedure. The softness of the C-loop haptics of this IOL type may also play a role in the decentration.

Comparison of a hydrophilic and a hydrophobic apodized diffractive multifocal intraocular lens.

Item does not contain fulltextTo compare outcomes between a new design apodized diffractive hydrophilic multifocal intraocular lens (IOL) (Seelens MF; study group), and a well-known apodized diffractive hydrophobic multifocal IOL (SN6AD1; control group). A comparative case series comparing refractive and visual outcomes at distance and near. Patient satisfaction with a validated questionnaire, dysphotopsia and straylight measurement scores were recorded at 3 months post-operatively. The study group comprised 48 eyes and the control group 37 eyes. At 3 months post-operatively the mean uncorrected distance visual acuity (UDVA) was not statistically significant different between the study group and the control group (0.02 +/- 0.07 logMAR [SD] vs 0.04 +/- 0.09 logMAR). Corrected distance visual acuity (CDVA) was statistically significantly better with the study lens (-0.04 +/- 0.05 logMAR vs -0.01 +/- 0.04 logMAR (p < 0.019). There was no clinical or statistical significant difference at the 40 cm distance (0.09 +/- 0.12 logMAR vs 0.08 +/- 0.09 logMAR). The study group had statistically significant better uncorrected near acuity at 50 and 60 cm distances (p < 0.03 and p < 0.007, respectively). In terms of satisfaction the lenses performed equally. Halos were seen less often with the study lens. Straylight, as a parameter for visual quality, was significantly less with the study lens. Conclusion: The Seelens MF performs equally as well as the well-known SN6AD1 for UCDA and CDVA. The Seelens MF performs better at intermediate distance, and seems to allow for better depth of focus, and increased visual quality. More study is needed to corroborate the last finding.1 oktober 201
